Introduction

In today’s fast-paced digital world, user authentication plays a critical role in ensuring security and a seamless user experience. Traditional methods of password-based authentication and one-time passwords (OTPs) can be cumbersome and time-consuming, leading to user frustration and high drop-off rates. Enter OTPLESS – a revolutionary one-tap sign-in solution that utilizes WhatsApp for easy and secure user authentication. In this blog, we will guide you through the process of integrating OTPLESS into your JavaScript application, enhancing user experience, and boosting security.

Step 1: Install the OTPLESS SDK – Easy Integration with WhatsApp

Begin by installing the OTPLESS SDK on your website. Simply copy and paste the following script on your login page:

(html)
Secure login with WhatsApp button
<script type="text/javascript" src="<https://otpless.com/auth.js>"></script>

With successful installation, the OTPLESS widget (floater) will be visible on your login page, ready to transform the authentication process.

🚩Note: Ensure your application is served over HTTPS for the widget to load correctly. The widget may not function as expected on localhost or in incognito mode.

Step 2: Retrieve User’s Information – Seamless and Secure Authentication

Upon successful authentication, the user object will be returned to you. Implement the following script to retrieve and log the user’s information:

(javascript)
<script type="text/javascript">
 function otpless(otplessUser) {
  console.log(JSON.stringify(otplessUser));
 }
</script>

The user’s information will be logged in the console as follows:

{
 "token": "xxxxxxxxxxxxxxxxxxxxxxxxxxxx",
 "timestamp": "YYYY-MM-DD HH:MM:SS",
 "timezone": "+XX:XX",
 "mobile": {
  "name": "User Name",
  "number": "User Mobile Number"
 },
 "email": {
  "name": "User Name",
  "email": "User Email"
 }
}

🚩Note: The user object is returned only after all the authentication methods configured in the SDK have been completed. If multiple methods (e.g., mobile and email) are selected, all must be verified before the user object is returned.

Step 3: Completing User Authentication – Streamlined Process

Utilize the user details obtained from the previous step to authenticate the user according to your application’s specific business logic. Whether it’s creating a new user account (sign up) or verifying an existing user (sign in), the user information provided through OTPLESS simplifies and secures the authentication process.

Conclusion: Elevating Security and User Experience with OTPLESS

Integrating OTPLESS into your JavaScript application is a game-changer in user authentication. By enabling one-tap sign-ins through WhatsApp, you streamline the user experience, increase engagement, and boost trust in your application’s security.

Say farewell to complex passwords and time-consuming OTPs, and welcome a seamless, secure, and user-friendly authentication process with OTPLESS. Elevate your user experience to new heights and make your application stand out from the competition.
